| 摘 要： | 采用电弧离子镀的方式在不锈钢基片上制备了NiCrAlY涂层.对涂层样品进行了物相分析,表面形貌观察,测定微区化学成分,储能模量和损耗模量.结果表明,利用电弧离子镀的方法可以在不锈钢基底上获得均匀的NiCrAlY涂层.制备过程中的弧电流变化对涂层的表面形貌和化学成分有一定的影响,对涂层的物相结构影响不大.为研究NiCrAlY涂层的阻尼特性,通过储能模量和损耗模量的测试结果得到涂层样品的阻尼性能,结果表明NiCrAlY涂层能明显地提高基底的阻尼性能.

| Abstract: | NiCrAlY coatings were prepared on stainless steel substrates by arc ion plating technique.The coating samples were tested in phase,surface morphology,micro-determination chemical composition,storage modulus and loss modulus.The results showed that uniform NiCrAlY coating can be fabricated on steel substrate by arc ion plating technique.The variation of arc current during the preparation influenced the surface topography and chemical constitution of the coatings to a certain extent,while the influence on the sample phases was not observed.The testing results of storage modulus and loss modulus were obtained to study the damping characteristics of NiCrAlY coatings.It approved that the damping properties of the substrates are prominently ameliorated by NiCrAlY coating. |
